Activate the site collection publishing feature gives error: The content type “Page Layout” at “/teams/T200001/_catalogs/masterpage” is read only

Question

I have a sp 2010 site collection. When I try to activate the site collection "SharePoint Server Publishing Infrastructure" feature I got this error:

The content type "Page Layout" at "/teams/T200001/_catalogs/masterpage" is read only.

What is going wrong?

Answer 1

1. Go to Site Content Types, then, go to the Document Content Types section
2. Click Document in that section
3. Click Advanced on the Site Content Types for that content type
4. In the Read Only section of that page click YES
5. Click OK

Or

$w = get-web http://myweb
$list = $w.Lists["_catalogs/masterpage"]
foreach ($item in $list)

{$item.ReadOnly = $false
$item.Update()}

$w.Dispose()
